Table 6

Input parameters for the generation of the discrete fracture network (DFN) geometries.

Joint set	DFN parameters	Value
1	Mean dip (°)	80
	Mean length (m)	1.0
	Std. Dev. (m)	0.5
	Intensity P2	1
2	Mean dip (°)	10
	Mean length (m)	1.0
	Std. Dev. (m)	0.5
	Intensity P2	1

P2 = (sum of lengths)/area.
